In honor of National Engineers Week we’ll focus on the different ways Thornton Tomasetti’s technical staff make a difference in the world around us.
This sample problem shows a large, explosively-loaded steel plate. VistaDam simulation produced a realistic fracture pattern using a reasonable mesh of shell elements.
VistaDam, a ductile-fracture prediction module for large-scale, thin-walled metal structures, is part of the VistaMat Suite of software products for advanced material failure modeling. VistaMat Suite also includes VistaFire for predicting fire and other thermal effects on structures and VistaCal, which allows calibration of material model parameters, including VistaDam and VistaFire and other widely used material models. The Suite was developed on the basis of fundamental applied mechanics research conducted by Weidlinger Associates, which merged with Thornton Tomasetti in 2015, in support of several multiyear Office of Naval Research programs. The theoretical foundations of VistaDam Suite are based on the latest experimental observations and fundamental failure mechanisms.
